Rabbi Dov Lior says Jewish Law prohibits sterile couples from conceiving using non-Jew's sperm, as it causes adverse traits. On subject of single mothers he says, 'Child cannot be 100% normal'
Rabbi Dov Lior, a senior authority on Jewish law in the Religious Zionism movement, asserted recently that a Jewish woman should never get pregnant using sperm donated by a non-Jewish man – even if it is the last option available.
According to Lior, a baby born through such an insemination will have the "negative genetic traits that characterize non-Jews." Instead, he advised sterile couples to adopt.
